CONTROLLING-VALVE MECHANISM.

Specification of Letters Patent.

Patented Aug. 15, 1916..

Application filed October 2, 1915. Serial No. 53,782.

To all whom it may concern:

Be it known that I, FRANK 3N. SLAW, a citizen of the United States,residing at Steubenville, in the county of Jefferson and State of Ohio.have invented certain new and useful Improvements in Controlling- ValveMechanism, of which the following is a specification.

This invention relates to controlling valve mechanism for use inconnection with hydraulic operated elements, and has for its object toprovide a valve of such class in a manner as hereinafter set forth, withmeans for controlling the operation of an element, such as elevators,vertical movable doors on furnaces, table rolls in rolling mills, andfor any other purposes wherein it is found applicable.

Further. objects of the invention are to provide a controlling valvemechanism for the purpose set forth which is simple in its constructionand arrangement, strong, durable, eliicient and convenient in its use,readily set up and comparatively inexpensive to manufacture.

lVith the foregoing and other objects in view the invention consists ofthe novel construction, combination and arrangement of parts ashereinafter more specifically described and illustrated in theaccompanying drawings, wherein is shown an, embodiment of the invention,but it is to be'understood that changes, variations and modificationscan be resorted to which come within the;

scope of the claims hereunto appended.

In the drawings wherein like reference characters denote correspondingthroughout the several views :-Figure 1 is an elevation of a controllingvalve mechanism in accordance with this invention. Fig.-

2 is a vertical. sectional view. Fig. 3 is a section on line 33, Fig. 1,looking in the direction of the arrow. Fig. l; is a vertical sectionalview of a modified form.

Referring to Figs. 1 to 3 of the drawings 5 and 6 denote a pair of valvecasings and the former isformed with ports 7-'8 and 9-10, and the latterhas ports 1112,' and 13-14. The ports 9, 10 of the casing 5 open into anipple 15 to which is connected a water supply pipe 16. The ports 13,1-1 open into a nipple 17 to which is connected a water exhaust pipe 18.Arranged within each of the casings 5, 6, is a cylindrical valve 19having a vertically disposed passage 20.

parts Each of .the valves 19 has a projection 21 which extends in oneend of a casing and each of the valves 19 is furthermore pro vided'with. a stem 22 which projects outwardly from the other end of thecasing. Each of the valve casings 5, 6, at the top is flanged as at 23,2-1 and seated upon the flanged topsof the casings 5, 6, are the flangedends 25 of an areuate coupling member 26 provided with passages 27, 2S,and these latter extend from one end to the other end of the member 26.The passage 27 at one end opens into the port 7 and at its other endinto the port 12. The passage 28 at one end opens into the port 8 and atits other end into the port 11. The flanged ends 25 of the member 26 areconnected to the flanges of the casings 5, 6, by suitable securingdevices which fixedly secure said member 26 in position and furthercouple the casing 5 to the casing 6. The coupling member 26 is formedwith a pair of oppositely disposed nipples 30, 31, the former opens intothe passage 27 and the latter into a passage 28. Leading from the nipple30 is a conducting pipe 32 and leading from the nipple 31 is aconducting pipe 33. The conducting pipes lead to the element which is tobe operated, by way of example a hydraulic cylinder. Connected to theouter ends of each of the valve stems 22, is an operating lever, one ofwhich is indicated at 3% and the other at 35, the latter is extended andprovided with a handle 36. The lever 3-1 is formed with a series ofopenings 37 whereby a sectional coupling link 38 can be adjustablyconnected to the lever 31, through the medium of a pin 10. The latterprovides a pivot connection between one end of the link 38 and the lever3-1. The other end of the link 38 is pivotally connected to the lever 35as at 41. The link 38 is formed with a plurality of sections adjustablyconnected together by a threaded sleeve 42.

Referring to Fig. 1 of the drawings 43 and a l denote a pair of valvecasings and the former is provided with ports a5, 4:6 and the latterwith ports d7, 18. Arranged with in each of the casings 4:3, 4:4, is acylindrical valve 49, having a centrally disposed passage 50. The port46 of the casing 13 opens into a nipple 51 to which is connected asupply .pipe 52. The port 4:8 of easing 4% opens into a nipple 53 towhich is connected an exhaust pipe 5 1. The casing 43 has a portedextension which communicates with the port 45 and which is flanged as at56. The casing 4 1 has a ported extension 57 which is flanged as at 58.Connected to the flanges 56, 58 are the flanged ends 59 of a couplingmember (50, the latter being provided with a passage 61, whichcommunicates at one end with a ported extension 55 and at the other endwith a ported extension 57. The coupling member 61 connects the valvecasings 4. .3 and 44 together, as well as establishing communicationthere between, and said member 61 has a nipple G2, to which is connecteda conducting pipe 63. Suitable securing devices are employed forsecuring the coupling members to the ported extensions 55, 57. AlthoughFig. 4 does not illus trate an operating member for the valves 49, yetthey are operated by the same means as that employed in connection withthe valves illustrated in Figs. 1 and 2. It will be assumed that thesupply is had through the pipe 16 and that the valves 19 have beenshifted so that the passage 20 of the valve to the casing 5 willregister with the ports 7, 10 and the valve 1 9 to the casing G willhave its passage 20 register with the ports 11, 14. Under suchconditions a supply will be had to the element which will be operatedthrough the pipe 32 and an exhaust for said element will be had throughthe pipe 33. When the valves 19 are shifted in the opposite directionpassages 20 of said valves will register with the ports 8-9, 1213, and asupply would be had to the element which is to be operated through thepipe 33 and an exhaust would be had through the pipe 32.

Referring to F l the valves 4-9 are so set up that when the valve 49 inthe casing 43 is shifted for supply, the valve 49 in the casing H isclosed to exhaust and when the valve 4.9 in the casing 43 is shifted toclose supply, the valve ll) in the casing 4A is shifted to open theexhaust.

What I claim is 1. A controlling valve mechanism comprising a supplyvalve casing having a pair of ports leading to a source of supply, anexhaust valve casing having a pair of ports leading to an exhaust, eachof said casings further provided with another pair of ports, a couplingmember having a pair of passages for establishing communication betweenthe last mentioned pairs of ports, conducting pipes leading from saidpassages,

shiftable valves arranged in said casings and capable when shifted toestablish communication between a pair of ports of their respectivecasings to provide for supply through one of said passages and exhaustthrough the other of said passages, and adjustable means for operatingsaid valves simultaneously.

2. A controlling valve mechanism comprising a supply valve casing havinga pair of ports leading to a source of supply, an exhaust valve casinghaving a pair of ports leading to an exhaust, each of said casingsfurther provided with another pair of ports, a coupling member having apair of passages for establishing communication between the lastmentioned pairs of ports, conducting pipes leading from said passages,shiftable valves arranged in said casings and capable when shifted toestablish communication between a pair of ports of their respectivecasings to provide for supply through one of said passages and exhaustthrough the other of said passages, the ports of each pair of ports ofeach of said casings extending at an inclination in opposite directionswith respect to each other.

3. A controlling valve mechanism comprising a supply valve casing havinga pair of ports leading to a source of supply, an exhaust valve casinghaving a pair of ports leading to an exhaust, each of said casingsfurther provided with another pair of ports, a coupling member having apair of passages for establishing communication between the lastmentioned pairs of ports, conducting pipes leading from said passages,shiftable valves arranged in said casings and capable when shifted toestablish communication between a pair of ports of their respectivecasings to provide for supply through one of said passages and exhaustthrough the other of said passages, and means for operating said valvessimultaneously, the ports of each pair of ports of each of said casingsextending at an inclination in opposite directions with respect to eachother.

In testimony whereof I affix my signature in the presence of twowitnesses.
